HOT-WATER-CIRCULATING WASHING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 314,846, dated March 31, 1885.

Application filed April 15, 1884. (N0 model.)

To all whom it may concern: Be it known that I, ABRAHAM HUFFER, a citizen of the United States of America, residing at Hagerstown, in the county of Washington and State of Maryland, have invented certain new and useful Improvements in Hot-Watear-Circulating Washing-Machines, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention pertains to an improvement in hot water circulating washing-machines; and it consists in the novel construction, combination, and arrangement of the parts, substantially as hereinafter more fully shown and described.

In the accompanying drawing, the figure is a longitudinal sectional view of my improvement.

In the construction of my hot-water-circulating washing-machine I employ a washingmachine similar to that shown in my'patent of September 6, 1881, N 0. 246,777, and adapt to and connect therewith by means of suitable pipe or conduit connections, 0, the boilerfurnace B, for supplying it with hot water and resupplying it therewith at suitable intervals.

The boiler-furnace B may be constructed either round or square, and may be heated either with oil or any ordinary fuel, and it is provided with a water-jacket, G, and ash-pan D. The water-j acket 0 extends from the grate a up to the bottom of the fuel-supply door E, where it is closed by the rim or plate F. The boiler G, which is integral with the furnace and surmounts it, is strengthened by the inclined, or it may be conical, bottom G, which projects transversely beyond the walls of the ed,while increasing the heatingsurface of the boiler, also greatly strengthens it, and in order to economize the heat generated in the furnace it terminates at top in the vertical smoke-pipe H, which is arranged, as shown, to project through the boiler.

The inclined bottom thus construct- As in the operation of clothes-washing it is essential that the water, when it becomes sedimentary and unclean, be removed from the machine and clean water substituted, I provide the pipe I, having the valve 1, which connects the water of the boiler G with that of the water-jacket G, the horizontal plane of the jacket 0 being lower than the bottom of the washing-machine; hence, when it is necessary to remove unclean water from the washing-machine, the valve 1 being closed, the cock I at the lower part of jacket C is opened and the water flows from the washingmachine through jacket 0 and out of stop-cock I. This accomplished, a small quantity of water is permitted to flow through the jacket and out of cock I, to carry off the sediment, and cook I is then closed and valve 1 opened until the washing machine is resupplied through the jacket and conduit 0 with clean hot water,

whereupon valve 1 is again closed and the operation repeated when clean hot water is again required in the washing-machine.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

1. The combination of the washing-machine A and furnace B, having conduits 0, waterjacket 0, and boiler G, located on the furnace B and connected with the water-jacket, substantially as shown, and for the purpose described.

2. The combination of the conduits O, wa

ter-jacket C, and cock I furnace B, having door E, the boiler G, located on the furnace, and pipe I, having valve I, substantially as shown, and for the purpose described.

In testimony whereof I afiix my signature in presence of two witnesses.

ABRAHAM HUFFER.
